The new SpeedSentry Shield, from All Traffic Solutions, State College, Pa., with 15-in. digits is incredibly compact, measuring at just 24 × 17 × 3.12 in. and weighing only 22 lb, including its battery. Lithium-ion batteries provide longer life in a smaller package. It can use solar assist or AC supply for more permanent installations. The Shield’s welded aluminum enclosure, shatterproof shield, impact-absorbing corners and graffiti-resistant powder-coat make it even tougher than our regular SpeedSentry. Visibility remains high thanks to auto-dimming 30° LEDs that combine with glare-resistant, UV-protected Lexan for increased contrast and digit readability. It can be programmed simply with a wireless PDA or its onboard buttons.
